BUSINESS LAW (LAW101) LEGAL PROBLEM ASSIGNMENT

BUSINESS LAW (LAW101)
LEGAL PROBLEM ASSIGNMENT
Semester 1, 2021
Question
Imagine you are a group of lawyers working in the legal department of a large telecommunications company called -Gateway Mobile-. Gateway Mobile sells phone plans, handsets, and phone accessories in stores all over Australia.
The CEO of Gateway Mobile is Sarah Lee. Sarah has contacted your team for advice in the following memo:
Dear Legal Department, http://assignmenthelp4u.com/2021/04/11/business-law-law101-legal-problem-assignment/
I am seeking your trusted guidance about a few issues that have been on my mind lately. Could you please prepare a letter of advice about the following matters?
1. I have recently read about several ethical scandals in the media that have greatly damaged the reputations of some large companies. I want to learn from their mistakes and ensure that Gateway Mobile does not get caught up in anything similar. Can you identify two ethical issues that we could potentially face in our business and how we can take steps to prevent them? Are there any legal requirements aware of that relat to these ethical issues?
2. The demographic of our customers is getting younger and younger. With the rise of social media and apps like TikTok, we are seeing more teenagers walk through the doors of our stores to sign up to phone plans with lots of data. What does the law say about entering a contract with minors? Are our contracts with teenage customers still valid?
3. As you know, we often enter contracts with other businesses to supply corporate phone plans and handsets. Most of these contracts have been in place for years. I have heard that there have been some changes to contract laws to protect small businesses, and I am worried that our contracts might now be considered -unfair-. In particular, we usually provide standard form contracts that allow us to increase our prices whenever we want, as well as automatic renewal of the contract (unless the customer gives notice to terminate). Do I have anything to worry about?
I appreciate your prompt advice about the above issues. Please make sure you reference legislation, case law and journal articles in your response so I can go back to trace the source of your advice if I need more information.
Yours sincerely,
Sarah Lee

Comparison Of Two Field Methods In A Scientific Report/Paper Format

I have attached the File name lab 9 as a paper criteria.

There is the excel sheet too.

Minimum Content of the Scientific Report Title  The title should be a brief summary statement about your paper. Your title will be what is most commonly cited and will be the “target” of topical searches via the internet. Choose your words carefully. As short and as concise a title as possible is best.  Each student will come up with the title! You might consider waiting until after completing the report to finalize the title.

Abstract  Think of the abstract as a short summary of your paper that could stand-alone as a publication. The abstract should include, in order: a summary of the introduction, methods, results, and discussion. However, you may include only key results and key discussion points in the abstract. Do not include reference to figures and tables, and don’t use abbreviations. Don’t include references in the abstract. This is the hardest section of the paper to write, and should be written after you complete the other sections.  Minimum of 200 and maximum of 300 words in a single-paragraph format. Introduction  The introduction should include a detailed explanation about why you are doing the study, i.e., the basis for your study.  This section should include observations or results from previous studies that support the basis for your study, but not the results or discussion or conclusions drawn from the results of your project.  Follow these observations or results from previous studies with the questions or hypotheses of your study.  The introduction should end with a brief paragraph that summarizes the setting, scope, and justification or importance of the study. This is a lead-in paragraph to the rest of the paper.  Minimum of 1/2 page of text in length with one or more paragraphs. 2 Methods  Write the methods in the past tense.  This should be a detailed, step-by-step, description of how you did the study.  Include details on the equipment and materials used (see list below).  Include the approach to data analysis and cite any statistical or other applications used to input, manage, graph, or analyze the data.  Include citations for any standard or previously published methods used.  Write this section with enough detail that someone else could duplicate your study or conduct a similar study with only your methods section available.  Include a map showing the location, sampling area, and plot and belt transect in the sampling area.  Minimum of one page of text in length with multiple paragraphs. Results  This the “what you got” section.  Write the results in the past tense.  This sections includes any data or results tables and graphs you have.  This is a summary of your key results from data, graphs, and/or results of statistical analyses.  You are not required to include a statistical analysis(-es).  You are required to include summary statistics for each data set (plot and belt transect) including the mean, maximum, minimum, variance and standard deviation.  If you do include a statistical analysis (-es), include the result of each statistical analysis that supports a result(s) as below. o ….there was no statistically significant difference (df=9, p>0.05, t=3.89) between mean species diversity scores….  You are not drawing conclusions, stating reasons, or interpretations in this section; only stating what you found.  Minimum of one table that includes summary statistics for each variable by method.  Minimum of two graphs included in this section. Each graph not larger than 1/3 of a page. Insert the graphs in the text of the results section.  Minimum of one page of text in length with multiple paragraphs. Discussion  This is the section where you interpret and evaluate your results.  Explain how you results supported or did not support the objective(s), hypotheses, or stated purpose(s) of the paper.  Put your conclusions in scientific context by comparing to previous studies that had similar or even different conclusions.  End with implications of one or more of the conclusions for any future studies.  Minimum of ½ page with one or more paragraphs. 3 References Sited  Include full citations of the references cited in your paper, and only the references you included in text.  Only use journal articles (no books) as references, and a minimum of two references.  Use this format for each journal article reference. o Jones, J.
